To all whom it may concern:

Be it known that I, CHARLES E. LOMBARD, a citizen of the United States,residing at East Wilton, in the county of Franklin and State of Maine,have invented certain new and useful Improvements in Spinning andTwisting Machines, of which the following is a specification, referencebeing had to the accompanying drawings,

My invention relates to improvements in spinning and twisting machines.

One object of the invention is to provide an improved mechanism foractuating the fliers to build up the yarn upon the bobbins.

Another object of the invention is to provide a tension or brake devicefor the bobbin spindles. A

A further object of the invention is to improve and simplifytheconstruction of machines or apparatus of this character and therebyrender the same moredurable and efficient and less expensive.

With the above and'other objects in view, which will appear as thenature of the invention is better understood, the same consists of thenovel features of construction and the combination and arrangement ofparts hereinafter described and claimed, and illustrated in theaccompanying drawings, in which Figure l is a side elevation of myininroved yarn spinningand twisting machine; Fig. 2 is a top plan view,parts being broken away and in section, of the spinning and twistingmechanism; Fig. 3 is a rear end elevation of the same; Fig. 4 is adetail longitudinal section through one of the twisters or fliers andthe co-acting parts; Fig. 5 is a detail side elevation, on an enlargedscale, of portions of the builder mechanism; Fig. 6 is a detail verticalsection taken on the plane indicated by the line 66 in Fig. 5; and Fig.7 is a detail vertical section taken on the plane indicated by the line77 in Fig. 5.

In the drawings 1 denotes the main frame on which the spinning andtwisting mechanism is mounted and 2 denotes a supplemental frame (whichmay be made a part of the main frame) on which is mounted mechanism forfeeding the yarn or roving. The frame or support 2 has arranged withinit adjacent to its front or outer end a yarn feed drum 3 against theperiphery of which two yarn spools or drums 4, 5 are adapted to bear andto be rotated by reason of their frictional contact with the drum 3. Theupper supply spool 4 has at its ends pivots or trunnions 6 which bearagainst the upper edges of the inclined supporting arms 7 projectingfrom the opposite sides of the frame 2. The weight of the spool 4 thusholds itin contact with the feed drum 3. The lower yarn supply spool 5has at its ends pivots 8 which are removably engaged with hook shapedbearings formed in the lower ends of hanger arms 9 which are carried bya transverse shaft 10 arranged for rocking or oscillatory movement inbearing notches formed in the upper end of the arms or supports 7. Uponone end of the rock shaft 10 is a depending crank arm 11 between thelower end of which and the frame 2 is a coil spring 12. The latterswings the arm 11 inwardly and hence actuates the hanger 9 to press thespool 5 against the feed drum 3.

The strands of yarn or roving a from the upper spool 4 pass through asuitable transverse guide 13 and between an upper set of rolls 14, 15,16; and they lead to the fliers of the upper set of bobbins as presentlyexplained. The strands of yarn or roving b from the supply spool 5 passthrough a transverse guide 17 and between a lower set of rolls 18, 19,20; and they pass to the fliers of the lower set of bobbins. There is nodrawing action betweenthe drums 3, 14, 15 and 16 and the drums 18, 19and 20. The upper rolls 14, 18, of each of the two sets are supportedupon the two lower rolls of each set, which lower rolls are gearedtogether by providing an idler pinion 21 which meshes with pinions' 22on the shafts of said lower rolls. On the shafts of the rolls 16, 20,are gears 23, 24, both of which mesh with a gear 25 loosely mounted upona stub shaft 011 the frame 2. The gear 24 also meshes with an idler gear26 which in turn meshes with a gear 27 on the shaft of the feed drum 3.Carried by the gear 25 is a pulley 28 which is connected by a belt 29 toa cone pulley 3O loosely arranged on a stub shaft on the frame 2. Thecone pulley 30 is connected by a crossed belt 31 to a cone pulley 32loosely mounted on a stub shaft on the frame 2 and carrying a belt wheelor pulley 33.

Arranged upon the upper portion of the main frame 1 are transverselyextending upright supports or standards 34, 35, in which are arrangedupper and lower sets or horizontal series of spindles 36 which carryupon their outer ends the usual bobbins 37. Coacting with each of thebobbins is a flier 38 able builder frame or member 67.

constructed preferably as shown in Fig. 4 and comprising a head 39rotatably and slidably mounted upon the inner portion of the spindle 36and provided at its rear end with a tubular extension or shaft 40 andupon its front end with oppositely disposed rods ll arranged for slidingmovement in a grooved pulley 42 which latter is swiveled or mounted forrotation in the standard or upright 34. The outer ends of the rods 41are connected and one of them carries a hook 4.3 to receive the yarn orroving.

The fliers of the upper set of bobbins are driven by belts fist passedaround the pulleys L2 and an upper driving drum or roll at?) journaledin an extended front portion of the frame l. The fliers of the lower setof bobbins are similarly driven by belts L6 arranged between the pulleys42 and a lower drum or roll l7 journaled in the lower front portion ofthe frame 1. The shafts of the drums 45, T7, are provided with pulleysetS which are connected by belts 49 to a double pulley 50 fixed upon atransverse shaft 51, which latter is connected by a train of speed gears52 to a transverse shaft 58. On one end of the latter is a pinion 5 Lwhich meshes with a driving gear 55 on a main drive shaft 60 to whichlatter power may be applied in any suitable manner.

On the shaft 60 is a pulley 61 which is connected by a belt 62 to thepulley or wheel 33, so that the feeding mechanism upon the frame 2 willbe driven from the mechanism upon the frame 1.

The fliers 38 are reciprocated longitudinally of the bobbins for thepurpose of building up the yarn thereon, by rack bars 63, which havetheir forward ends rotatably and non slidably connected to the fliers,preferably, by providing them with sleeves 64 which are arranged uponthe tubular extensions or portions 40 of the flier heads and retainedthereon by collars This con- .nection of the forward ends of the rackbars is sutiiciently loose to allow their rear ends to have a slightvertical movement. Said rear ends of the bars 63, on the upper edges ofwhich are formed racks, project through a suitable opening in the rearsupport or upright 35 and also through openings in a transverse guidebar 66 arranged in a mov- The latter preferably mounted for swinging oroscillatory movement at the rear of the main frame 1 and as shown is ofsubstantially U- shape consisting of two depending side plates or arms68 fixed at their lower ends upon a transverse rock shaft 69 suitablyjournaled on the frame 1 and having their enlarged upper portionsconnect-ed by the guide 66 and a cross piece 67 The guide (36 holds therack 63 in mesh with pinions 71 'on a transverse shaft 72 iournaled inbearings in the side plates 68 of the builder. On

one end of the shaft 72 is a worm gear 73 adapted to mesh with a worm 74on one end of a shaft 45 journaled in suitable bearings on a retractablesupport 76 which is preferably in the form of a plate pivoted at itslower end at 77 on one of the arms or side plates (38 and adapted tohave its upper end secured to the upper portion of the latter by aclamping screw 78 or an equivalent clamping or securing device. Bypivoting the support or plate 76 it will be seen that the worm 74 whichit carries may be moved out of mesh with the gear 73 so that the racks(33 may be drawn inwardly in resetting the builder mechanism ashereinafter explained. The shaft is prevented from moving in onedirection, preferably, by fixing to it a ratchet wheel 79 which isengaged by a spring actuated pawl or dog 80 pivoted at 81 upon the plateor support 76; and said shaft is rotated in the other direc tion by theengagement of a gear 82 with a stationary rack 83 arranged upon the mainframe and preferably upon the upright or standard The gear 82 is looseupon the upper portion of the shaft 75 but is connected to it forrotation in one direction by a. pawl and ratchet device consisting of aratchet wheel 84 fixed on the shaft and adapted to be engaged by aspring actuated pawl or dog pivoted upon said gear. This pawl andratchet coni'iection between the gear and the shaft allows the former toturn in one direction without rotating said shaft and hence withoutactuating the shaft 72 and the racks 63, while the last mentioned partswill be actuated when the gear 82 is rotated in the opposite direction.

The rock shaft or pivot (39 for the flier is actuated so as to rock oroscillate the latter by means of a heart shaped cam 86 arranged on themain drive shaft (30 and adapted to have its periphery engaged by ananti-friction roller 87 on a lever 88 suitably pivoted at 89 in theframe 1. The lever 88 has an arm 90 which is connected by a link 91 to acrank arm on the shaft (39.

For the purpose of varying the speed of the bobbin carrying spindleswhile the yarn is being wound upon different portions of the bobbins Iprovide a tension or friction brake device for said spindles. Thisdevice consists of a friction disk or wheel 93 arranged upon theprojecting rear end of each of the spindles 3(5 and adapted to beengaged by a brake spring 94 arranged upon a slidable operating bar 95.The bar 95 is preferably arranged upon the rear face of the upright 35between the upper and lower sets of spindles as more clearly shown inFig. 3, and the springs or resilient brake shoes 9% project upwardly anddownwardly from said bar so as to engage the disks 93. The pressureexerted by the springs SH against the disks is adapted to be regulatedby set screws 96 arranged in studs or projections upon said bar andadapted to impinge against said springs as shown. One end of the bar 95is connected to one arm of a bell crank 96 pivoted at its angle at 97 onthe frame 1 and having its other arm connected by a link 98 to a crankarm 99 on the rock shaft (39.

The operation of the machine is as follows: The spools 4t, .5,containing the yarn or roving are properly supported as shown in Fig. 1and the strands a b are passed through the guides and the rolls on theframe 2 and after being engaged with the hooks 43 of the fliers areattached to the bobbins. Power is applied to the main drive shaft 60 andthe various parts of the machine receive their motion from said shaftthrough the gearing above described. The supply spools or drums 4, 5,being pressed, the former by gravity and the latter by the spring 12,against the positively driven drum 8 are rotated by the latter and thestrands of yarn a b are fed to the guides and the upper and lower setsof rolls as will be readily understood. Owing to the provision of thespeed gearing 52 between the main shaft 60 and the shaft 51 from whichthe rolls 45, &7 are driven, the fliers will-be driven at a higher rateof speed than the bobbins and hence the strands of yarn will bethoroughly twisted before being wound upon the bobbins. The heart shapedcam 86 will oscillate the lever 88 and the movement of the latter willbe imparted through the intermediate connections to the rock shaft 69 towhich the builder frame or member 67 is connected, and hence the latterwill be oscillated. This oscillation of the builder causes the rack bars63 and hence the fliersto be reciprocated; and owing to the engagementof the gear 82 with the stationary rack 88, said gear will be oscillatedand when it rotates in one direction the worm shaft 75 will turn with itand will actuate the shaft 72 carrying the pinions 71, consequently saidracks will be moved forward a little more than the length of the rockingmovement of the builder, and the fliers willbe gradually movedlongitudinally of the bobbins so that the yarn will be wound evenly uponthe bobbins. When the gear 82 rotates in the opposite direction it willturn independent of the worm shaft 75, which latter will be held againstrotation by the pawl 80 and the ratchet 7 9. The movement of the rockshaft 69 is also imparted through the parts 99, 98 and 96 to the bar 95so that the latter will be reciprocated and will vary the tension of thebrake springs 94 upon the brake disks or wheels 93 on the bobbincarrying spindles. The operation of these parts is so regulated thatwhen the yarn is being wound upon the small 'or tapered part of thebobbins the bar 95 moves outwardly to relieve the tension of the brakesprings upon. the brake disks or wheels and when the yarn is being woundupon the larger portions of the bobbins the friction is increased by themovement of said bar in the opposite direction. After the bobbins arefull, the screw or fastener 78 is operated to release the plate orsupport 7 6 which may then be swung to disengage the worm 74 from thegear 7 8 so that the racks 63 may be drawn rearwardly and reset.

It will be understood that any suitable mechanism other than the oneillustrated and described may be used in connection with my improvedbuilder mechanism for feeding the yarns thereto and that the bobbins maybe disposed either vertically or horizontally according to the characterof the feeding device or mechanism.
